Installing a sonar on an inflatable boat is not just a matter of comfort, it's a necessity for a serious angler who wants to understand the bottom relief and find fish. PVC-boat They require a special approach to installation of equipment because of their flexible design and low resistance to mechanical damage. Incorrect fixation can lead to the loss of expensive equipment or damage to cylinders at the most inopportune time.
The main difficulty is to find a balance between the rigidity of the attachment and the elasticity of the side, which constantly changes its shape under the load and pressure of water. TranduserThe graph, or sensor, must be in the water at a certain angle so that the emitted signal goes perpendicular to the bottom, not to the side. Errors in the planning stage often lead to the appearance of "dead zones" on the screen or the complete absence of the signal when moving.
In this article, we will take a look at all the details of the installation, from the selection of the location to the final calibration, so that your fishing season goes smoothly. Properly installed system will allow you to feel confident on the water and focus on the main thing - catching the trophy.
Choosing the optimal location for the sensor installation
The first and most critical step is to determine the mounting point, which is the quality of the image on the display. The ideal place should be in the zone of calm water flow, where there are no swirls from the elements of the boat design or the operation of the engine. Most anglers choose the starboard side, because this makes it easier to control the tackle with the left hand, but the final decision depends on the layout of your boat.
It should be borne in mind that when the boat moves, PVC can slightly deform, especially on the wave, so sounder It should not be a rigid element like a stringer or a can. If you plan to use a boat with an outboard motor, place the emitter closer to the transom, but not directly under the propeller jet to avoid cavitation interference.
Inflatable boats have a problem with the sidewalking, so the mounting position should be as stable as possible, so you should not attach the sensor to the nose, where the shocks to the wave will be maximum, or too close to the stern, where the flow of water is turbulent.
⚠️ Warning: Never install the sensor in the area of direct contact with inflatable tubes without additional protection, as with a strong distance on a solid object, the sharp edges of the attachment can damage the PVC fabric.
Types of inflatable boat anchorages
The market offers many fixation solutions, but not all of them are suitable for the soft shell of an inflatable vessel. Standard rods used on rigid hulls are useless here, and even dangerous. You will need specialized solutions designed with the flexibility of the board in mind.
One of the most popular options is swivel-powered suction cups, but their reliability depends on the quality of the rubber and the purity of the surface. A more reliable but time-consuming method is the use of inflatable platform holders that are fixed by slings to the rims or D-rings of the boat. There are also magnetic mounts, but their use on PVC is possible only in conjunction with additional rigid inserts inside the cylinder, which is rarely justified.
- 🎣 Suctions: They are easy to install, but can be unstuck at high speed or at low temperatures.
- 🎣 Inflatable platforms: They provide stable position and depreciation, but require space to be placed inside the boat.
- 🎣 Rigid brackets per transom: The most reliable option, requiring drilling or the use of powerful temporary clamps.
When choosing a method, remember that fixation It has to withstand not only the weight of the sensor itself, but also the dynamic loads that arise when you move along the wave. Cheap plastic holders often break down in the first season, leaving the angler without a sonar.
Installation tools and materials
Before you start, you need to prepare the entire arsenal of tools to make the process go smoothly and without interruptions. For a quality installation, you will need not only the sensor itself, but also auxiliary materials that ensure tightness and durability of the connection.
Be sure to check the equipment of your sonar: some manufacturers do not include in the set fasteners for inflatable boats, and they have to be purchased separately. Pay special attention to the length of the cable, as a standard length of 6 meters may not be enough to place the control unit in a convenient place for you.
- 🔧 Tools: Drill (if stationary installation is planned), screwdrivers, scissors, degreaser.
- 🔧 Materials: Silicone sealant, reinforced scotch, PVC glue, cable screeds.
- 🔧 Defense: Corrugated cable, shrinkage, tape.
If you decide to insert the sensor directly into the boat (which is rarely done and only by experienced craftsmen), you will need a special cutter and confidence. In most cases, PVC boats use external installation, which does not require violation of the integrity of the cylinders.
☑️ Preparation for installation
Step-by-step installation instructions
The installation process begins with careful marking and fitting, spread all the elements on a dry and clean surface of the boat to visually assess the trajectory of the cable and the point of release of the sensor into the water. Take your time to fix the elements dead, first conduct a test assembly.
If you use suction cups or a platform, make sure the surface of the balloon is completely clean and dry. Any grain of sand or drop of fat will reduce adhesion. When using adhesives, follow the manufacturer's instructions, withstanding the necessary polymerization time before launching.
| Work segment | Action | Important nuances |
|---|---|---|
| 1. Markings | Determination of the installation point | Consider the angle of entry into the water |
| Preparation | Cleaning and degreasing | Use alcohol or special equipment |
| 3. Fixation | Holder anchorage | Checking clutch reliability |
| 4. Cable laying | Laying the wire to the block | Protection against overbending and water |
Once the sensor is physically installed, you need to put the cable in the right way, so it doesn't have to hang around or create a loop that you can grab with your foot or your tackle, and use clips or Velcro straps to fix the wire along the side.
⚠️ Caution: You can not pull the cable "into the string", always leave a small margin of length to compensate for the movement of the boat and vibration, otherwise the contacts inside the wire may move away.
Protection of cable and connections
Water and electricity are dangerous combinations, so sealing the joints should be given the utmost attention, even if the sonar connectors are marked. IP67 or IP68Long stays in salt water or under jet pressure can lead to oxidation of contacts.
Use adhesive-layered shrink tubes to insulate any compounds you've made yourself. Standard water insulation doesn't last long: it unsticks and slides. For added protection, you can put the cable in a flexible corrugated corrugated tube that will keep it from ultraphylete and mechanical damage.
How to protect the connectors from salt?
If you fish at sea or salt estuaries, after each fishing, be sure to wash the connectors with fresh water and spray them with a water-repellent spray (WD-40 or analog) to displace the moisture residue and create a protective film.
Pay special attention to the place of entry of the cable into the hull of the boat, if you have made a through hole. sealantIt's ultraviolet resistant and temperature resistant, and regular silicone can crack over time, so it's better to use polyurethane compounds.
System setup and calibration
After installation and first descent, you need to calibrate the sonar. In the menu settings, select the type of sensor installed, if this does not happen automatically. It is important to set the depth of the transducer installation correctly so that the instrument correctly displays the depth and does not confuse the bottom with air bubbles.
Do a test swim at different speeds, and if there's a random noise or a signal goes missing, try changing the angle of the sensor, and sometimes you just need to rotate it a few degrees so that the flow of water starts to flow around the working surface without vortexes.
- ⚙️ Sensitivity: Adjust the sensitivity level so that you can see the fish, but cut off the bottom debris.
- ⚙️ Frequency: For small depths, use high frequency (200 kHz), for large depths, low frequency (50 kHz).
- ⚙️ Update speed: Increase the speed of updating the image when actively searching for fish.
Don't forget that calibration The process is different for each boat and operating conditions, and what works on a calm lake may require adjustment on a fast river.
Frequent errors in installation
Many anglers step on the same rake, ignoring basic rules of physics and mechanics, and the most common mistake is mounting the sensor too high relative to the water level, resulting in air capture and loss of signal during acceleration.
At the other extreme, the installation is too low when the sensor protrudes over the keel line, which ensures it encounters underwater obstacles, snags or rocks, which often breaks down. Safe zone It is a balance between depth of immersion and protection from impact.
The direction of the boat is also often ignored, and the sensor has to look backwards as it moves, and if it's skewed to the left or right, the echo will go sideways, and you'll be blind to what's right under the boat.
⚠️ Warning: Do not try to glue the sensor directly to the cylinder fabric without a hard pad - vibration at speed will quickly destroy the adhesive seam, and the equipment will be overboard.
The main secret of successful installation is testing the system at low speed before entering the main fishing mode, which allows you to identify and eliminate installation defects without the risk of losing equipment.
Maintenance and care of the system
After every fishing trip, especially in salt water, the system needs to be washed with fresh water, the salt aggressively affects the metal parts of the attachment and the plastic elements of the sensor body, and regular care will extend the life of the equipment many times over.
Before long storage, remove the sensor, dry the cable and connectors, store the equipment in a disassembled form, without tension of the cable, in a dry room. Periodically check the condition of the fasteners: suction cups can dry out, and plastic latches can lose elasticity.
Timely replacement of worn-out mounting elements will be cheaper than buying a new sonar. Keep an eye on the integrity of the cable insulation: any cracks must be fixed immediately, or water will get to the copper.
Frequently Asked Questions (FAQ)
Can I attach the sonar sensor to the nose of the PVC boat?
Technically possible, but highly discouraged, the nose is hitting the maximum wave load, causing the sensor to continuously capture air and lose signal, and the cable will interfere with boat control and fishing.
At what height from the bottom of the boat should the sensor be?
The optimum depth of the sensor is 15-30 cm below the water level when the boat is stationary. When moving, the boat crouches, and this margin is usually enough to keep the sensor in the water, but does not create excessive resistance.
Will the echo sounder prevent the presence of an outboard motor?
The motor can interfere if the sensor is in the bubble zone of the propeller's water, so it's important to carry them to the sides or to place the sensor strictly in the center of the transom, if the boat and motor design allows it, or to use remote mounts.
Do I need to lubricate the suction cups before installation?
Special suction greases can improve adhesion, but often pure water is enough. Using oils or petroleum petroleum jelly can, on the contrary, worsen adherence to the PVC material or damage its structure over time.
How often should I change the sealant on the stationary fastener?
It is recommended to check the condition of the sealant before each season. If you notice darkening, cracking or detachment, the layer must be completely removed and re-applyed. On average, a quality sealant lasts 2-3 seasons.
